Access Point Name
(also APN)
Access Point Name definition
An Access Point Name is a setting used by mobile devices, such as smartphones, tablets, and smartwatches, that allows the device to access the internet. It identifies the network provider and type (GSM, GPRS, 3G, 4G) and acts as a “gateway” between the cellular network and the internet.
The APN is used in processes such as:
- Assigning an IP address to a device
- Determining which kind of network is needed
- Implementing security standards
The most common Access Point Name in the US is “wholesale.”
Access Point Name change
Typically, the APN information is filled in automatically when the SIM (or eSIM) card is inserted, and the user does not have to do anything with it to be able to access the internet. If the device has connection issues related to the APN, it is recommended to reset the network settings.
The Access Point Name settings can be modified. However, the correct values vary depending on the phone and network.
